ver_linux: e2fsprogs, look for numerical input, not field number

Browse source 
Rely on regex to find the version number, rather than rely on numerical input to be found in a particular input field.
Proposed implementation also eliminates the necessity to invoke 'grep' + 'sed' + 'awk'.

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
